CentOS 7 安裝Nginx 並配置自動啟動
1、官網下載安裝包
http://nginx.org/en/download.html,選擇適合Linux的版本,這裡選擇最新的版本,下載到本地後上傳到伺服器或者centos下直接wget命令下載。
切換到/usr/local目錄,下載軟體包
1 2 |
# cd /usr/local
# wget http://nginx.org/download/nginx-1.11.5.tar.gz
|
2、安裝nginx
先執行以下命令,安裝nginx依賴庫,如果缺少依賴庫,可能會安裝失敗,具體可以參考文章後面的錯誤提示資訊。
1 2 3 4 5 6 7 |
# yum install gcc-c++ # yum install pcre
# yum install pcre-devel
# yum install zlib
# yum install zlib-devel
# yum install openssl
# yum install openssl-devel
|
解壓安裝包
1 |
# tar -zxvf nginx-1.11.5.tar.gz
|
nginx被解壓到了/usr/local/nginx-1.11.5 目錄下(不要把壓縮包解壓到/usr/local/nginx目錄下,或者將解壓後的目錄重新命名為nginx,因為nginx會預設安裝到/usr/local/nginx目錄下),切換到nginx-1.11.5/目錄
1 |
# cd /usr/local/nginx-1.11.5/
|
執行# ./configure
1 |
# ./configure
|
該操作會檢測當前系統環境,以確保能成功安裝nginx,執行該操作後可能會出現以下幾種提示:
checking for OS
+ Linux 3.10.0-123.el7.x86_64 x86_64
checking for C compiler ... not found
./configure: error: C compiler cc is not found
如果出現以上錯誤提示資訊,執行yum install gcc-c++安裝gcc,
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.
如果出現上面提示,表示缺少PCRE庫
./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library
statically from the source with nginx by using --with-zlib=<path> option.
如果出現以上提示,表示缺少zlib庫
如果沒有出現./configure: error提示,表示當前環境可以安裝nginx,執行make和make install編譯nginx
1 2 |
# make
# make install
|
沒有出錯的話,表示nginx已經成功安裝完成,預設安裝位置為/usr/local/nginx,之前的/usr/local/nginx-1.11.5/可以刪除掉了。
如果出現cp: 'conf/koi-win' and '/usr/local/nginx/conf/koi-win' are the same file,可能是你把安裝包解壓到了/usr/local/nginx目錄,解決辦法是將該目錄重新命名為其他名稱後再執行make,make install.
3、配置nginx開機啟動
切換到/lib/systemd/system/目錄,建立nginx.service檔案vim nginx.service
1 2 |
# cd /lib/systemd/system/
# vim nginx.service
|
檔案內容如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
[Unit]
Description=nginx
After=network.target
[Service]
Type=forking
ExecStart= /usr/local/nginx/sbin/nginx
ExecReload= /usr/local/nginx/sbin/nginx reload
ExecStop= /usr/local/nginx/sbin/nginx quit
PrivateTmp= true
[Install]
WantedBy=multi-user.target
|
退出並儲存檔案,執行systemctl enable nginx.service使nginx開機啟動
1 |
# systemctl enable nginx.service
|
systemctl start nginx.service 啟動nginx
systemctl stop nginx.service 結束nginx
systemctl restart nginx.service 重啟nginx
4、驗證是否安裝成功
輸入http://伺服器IP/ 如果能看到nginx的介面,就表示安裝成功了
